Please solve the following Problem:
You need to store and manage Payroll Records stored as an array of structures of the following form:
struct payroll {
unsigned long long int internal_id;
char first_name[50];
char last_name[50];
char department[100];
unsigned char dob_day;
unsigned char dob_month;
unsigned short dob_year;
double monthly_salary;
};
The array of structures is stored as an external variable
#define MAX_PAY_RECS_NO 10000
struct payroll pay_recs[MAX_PAY_RECS_NO];
The number of actual payroll records is stored in the following external variable:
size_t pay_recs_no;
